@farsmile90 - I might be misunderstanding you, but just in case - code from other layouts, while in memory, does not run unless included, so don't worry about code from other layouts hitting the framerate.

Not unless they're included. But any data - tiled backgrounds, sprites, sfx I guess, will be held in memory all the time at the moment. This is why you get high memory usage warnings from the browser (or at least I do)
